Skar Audio introduces its SK series line-up of high-performance subwoofer enclosures to bridge the gap between competition-grade quality and universal fit pre-fabricated enclosures. The SK3X12V is a triple 12-inch, universal fit, ported subwoofer enclosure. Featuring three independent subwoofer chambers, we engineered this enclosure to produce incredibly accurate and responsive low-end frequency response. In addition, each chamber features its own slot port alongside the bottom of the enclosure, which is tuned for the optimal compatibility and performance of most 12" drivers.
When setting out to offer a line-up of premium, universal fit, subwoofer boxes, the end goal was to deliver a final product that was unlike anything else available on the market; setting new standards for quality and performance. The enclosure features a kerf style port, which means that the port construction utilizes the curves typically found only in custom, high-end, professional enclosures, allowing the box to offer deeper and more accurate bass. Furthermore, it’s precisely tuned to ensure that it delivers riveting low-end frequency response and the type of bass that turns heads from outside the vehicle.
The differentiating features that put this box in a league of its own don't stop there though; this triple 12-inch vented enclosure also utilizes high-end materials during construction, ensuring durability and reliability. On top of its outstanding craftsmanship, this box is also braced for extreme strength, and can handle even the most brutally powerful subwoofers. Internally, we line several walls of the enclosure with poly-fill to enhance the overall versatility and depth of sound that this enclosure reproduces with any given subwoofer. The premium push terminal wiring cup, that is built into the side of the enclosure, features 16-gauge speaker wire that is pre-soldered and connected to the terminals, making it easier than ever to wire up and install your subwoofer.

    Perfect set up. Comes with wires already wired up in the box just wire your sub and install easy as that. This box really bumps with 3 DDX 12 2 ohm subs. Pounds like crazy. Running

    The box is a good well made box but it doesn't have as low of bass that the 2 12s SDR box did. The box was a little weird to wire because each speaker is in its own chamber but it

    I am using this triple 12 sub box for 3 JL Audio 123V3 4. They are wired at 2.7 ohms and sound great in my 2018 Cadillac XTS. The box fit great but is a pain to get in the truck.
